DECARBONIZER Filecz April 17, 1931 g wuentow Patented july 4, 1933 UNITED STATES PATENT OFFICE JOSEPH ZUBATY AND LUCIAN B. SMITH, OF FLINT, MICHIGAN, ASSIGNORS T A C SPARK PLUG COMPANY, OF FLINT, MICHIGAN, A COMPANY OF MICHIGAN DECARBONIZER Application led April 17,

This invention relates to carbon removing devices for use on internal combustion engines, particularly the engines of automotive vehicles.

The object of the invention is to provide a device which will supply a liquid carbon removing compound to the combustion cham ber and cylinders of the engine to remove the carbon therefrom.

In carrying out the invention, a bracket is mounted at thedashboard of an antoniotive vehicle. `A container holding a carbon remover is removably mounted on the bracket and a pipe connects the bracket and container I to the intake manifold of the engine. A reciprocable plunger, spring held in one of its extreme positions, is mounted on the bracket and is adapted to be inwardly pressed to puncture or make a hole in the container which will allow the liquid carbon remover to flow from the container and be drawn into the intake manifold for delivery to the combustion chamber and cylinders of the engine.

The bracket has a special configuration and is provided with a recess. The container has an extension which tits into the recess when the container is mounted on the bracket. The slidable plunger has a pointed or sharpened edge which is adapted to pierce or make a hole in the extension to allow the carbon remover to flow from the container. When the plunger is inwardly pressed to pierce the container walls, the liquid flows from the container into a space between a reduced portion of the plunger and the wall of the bracket in which the plunger is mounted. lVhen in inwardly pressed position, the reduced portion mates with an opening in the bracket, which opening is connected to the pipe which delivers the compound to the manifold. The plunger is also provided with a bore which extends in an axial direction thereof and also has an opening which communicates with the bore. When the plunger is inwardly pressed, the plunger opening mates with an opening in the bracket to allow air to iow to the interior of the container. The purpose of this air low is to prevent the formation of a vacuum in the container and to allow for a Serial N o. 530,872.

the internal combustion engine of an automotive vehicle.

Figure 2 is a sectional view through the bracket and container separated from the vehicle.

Figure 3 is an enlarged sectional view of a portion of the structure of Figure 2 but showing the plunger depressed.

Figure 4 is a perspective view of the cutting end of the plunger.

Referring to the drawing, the numeral 2 indicates an automotive vehicle as a whole. 'l'he vehicle has the usual dashboard 4, toe board 6, and floor board 8. Theengine is indicated as a whole at 7 the fan at 9, the fan pulley at 10. The engine has the usual intake manifold 12, the carburetor 14 and riser 16 leading from the carburetor to the manifold. The exhaust manifold is shown at 18.

The bracket 20 of the carbon remover of the invention is mounted on the dashboard 4 and secured in place by means of bolts and nuts l1 fastened through the openings 19 in a Wall of the bracket.

The bracket has the shelf portion 22 eX- tendng horizontally from the Wall of the bracket and a recess 24 is provided as shown in Figures 2 and 3. The bracket has the lateral ears 26 and the container for holding a. carbon remover 28 is seated on the bracket. The container has the extension 30 at one of its ends, which extension is adapted to fit in the recess 24. A suitable gasket 32 is positioned between the container and the shelf 22 and rests in a groove 34 in the shelf. The strap 36 extends over the top of the container and has slots or openings in its ends for the reception of the screwthreaded ends of bolts 38. The Shanks of the bolts are passed through openings in the ears 26. Wing nuts 40 are screwed on the threaded ends of the bolts and firmly press down on the strap 36 rigidly to hold the container in place on the shelf 22.

The bracket 20 is provided with a bore 42, a portion of which is enlarged at one end as indicated at 44. The bracket has the opening 46 communicating with the bore 42 and a second opening 50 for the reception of a guiding pin 48. A plunger 52 lits into and is adapted to slide in the bore 42. lhe plunger has the elongated slot 54 1n which the end of .the pin 48 is recelved. The p1n 48 and slot 54 prevent the plunger from -rotating in its bore 42 but permit of 1ts reciprocation within the limits of the slot.

At the junction of the enlarged portion 44 with the bore 42 proper, a packing 56 is provided. The packing is held in position by means of the member 58 and by the coil spring 60 retained about the plunger 52 between the member 58 and the plunger head portion 62. The spring 60 urges the plunger 52 to the position shown in Figure 2.

The plunger 52 is hollow or has a bore 64 at its inner end and has an opening 66 which leads to the bore 64.

The extreme inner end of the plunger is tapered as shown at 68, the tapered ortion having a sharp edge 70, the purpose o which is to cut, puncture or make a hole in the eX- tension of the container 28 when the plunger is inwardly pressed, as shown in Figure 3.

The plunger has a reduced portion 72 intermediate its ends but formed closely adjacent the tapered end 68. The urpose of the reduced portion 72 is to allow or the outflow 'of the carbon remover when the hole has been punched by the inward movement of the plunger.

The bracket is provided with an opening 74, a portion of which is screwthreaded for the attachment of the pipe 76 which leads to and is attached substantially to the central portion of the intake manifold 12 as at 78. When the plunger isin its innermost position as shown in Figure 3, the reduced portion 72 will mate with the opening 74 to allow the carbon remover in the container 28 to flow to the engine.

When the plunger is in its innermost position as shown in Figure 3, it is also to be noted that the opening 46 in the bracket 20 mates with the opening 66 leading to the bore 64 of the plunger 52. The purpose of this structure is to allow air to enter the openin 46 and pass through the opening 66 and ore 64 to the interior ofthe container. If no air passage were provided, the ilow of the carbon remover to the engine would tend to create a vacuum in the can and necessarily retard the flow.

The operation of the device is as follows:

When the automobile reaches the end of its run and is standing in the garage, the engine is not shut olf but is allowed to continue to run at a relatively high speed with substantially closed throttle. The operator then presses his foot on the head 62 of the plunger and forces it inwardly from the position of Figure 2 to that of Figure 3. This will puncture the container and make an opening 77 therein and, owing to the high suction in the intake manifold l2, the carbon remover 78 in the container' 28 rapidly will be withdrawn through the chamber or passage formed by the reduced portion 72, through the opening 74 and pipe 76, into the intaker manit'old l2 and to the combustion chamber and i-.vlinders of the engine. Owing to the high degree of suction or pull exerted on the carbon remover by the suction in the intake manifold, the air i rom the outside will freely enter through the openings 46 and 6G to the bore 64 and into the container so that all of the liquid in the container 28 quickly will be discharged into the engine. The container' 28 contains onli enough carbon remover or carbon solvent for one charge and when this charge has been delivered to the engine, the. engine will choke and stop. The carbon remover is allowed to remain in the engine-for a considerable period. To allow the carbon remover to stand over night is sufficient and desirable. In the. morning, the engine is started in the usual way and owing to the action of the carbon remover or carbon solvent. the Carbon in the combustion chamber and cylinders has been dissolved or loosened so that it will now be forced out of the engine into the exhaust pipe by the. operation'of the engine in the usual way.

After the can has been exhausted of its contents, the wing nuts 40 are loosened to allow the removal of the strap 36. The container is then removed and thrown away and a new container put in its place. The device is now ready for a second operation and may be used when desired.
